[TriLUG] iscsi setup

[Jason Tower]

anyone have experience with iscsi on linux (both initiators and targets)? 
trying to find out some best practices for running a backend server (iscsi 
target) to multiple clients (initiators).  any significant pros/cons to 
using iscsi specific hardware HBAs?  the transport will probably be 100mb 
ethernet to start, moving to gigabit as needed.

also, what options exist for backing up my primary iscsi target to another 
system?  are there tools that provide rsync-like capabilities but at the 
block instead of the file level?
